Yellow fever is a viral disease, found in tropical regions of Africa and the Americas. It principally affects humans and monkeys, and is transmitted via the bite of Aëdes mosquitoes. It can produce devastating outbreaks, which can be prevented and controlled by mass vaccination campaigns.

Travellers from Zambia; Tanzania; Eritrea; Somalia; Sao Tome and Principe will no longer be required to produce proof of the yellow fever certificate when coming to South Africa after they were included on the World Health Organization Low - risk yellow fever countries list.

These are areas where the virus is present in monkeys and is a potential risk to humans as defined by the World Health Organisation. Some of these countries demand a yellow fever certificate from travellers as a condition of entry to their country. Many of these, and other countries, will ask you for a certificate if you are entering from an infected country.
